Analysis Summary
Japan's Meteorological Agency announced a new official term—kokushobi (cruelly/brutally hot)—for days reaching 40°C or hotter, following record-breaking summer heat in 2025 that shattered records going back to 1898. Summer 2025 saw nine days above 40°C nationwide and a peak of 41.8°C in Isesaki, with cities like Kyoto experiencing 52 days above 35°C versus a historical average of 18.5 days. This linguistic shift reflects a structural reality: extreme heat is becoming frequent enough in Japan that meteorologists needed dedicated terminology, and forecasters expect above-normal temperatures again this summer, suggesting this is now the baseline rather than an anomaly.
